Happy Birthday, Pattie Boyd and Patti Hansen!

One was discovered at sixteen selling hot dogs on the beach in Staten Island, the other was a nineteen-year-old model cast as a schoolgirl on a train in A Hard Days Night. Oddly enough, these two titans of the rock chick hall of fame—Patti Hansen and Pattie Boyd—share more than a name; they share the same birthday (which may seem deeply meaningful for believers in astrology, but think about it, plenty of people born on March 17 are not beautiful).

So happy birthday to Patti and Pattie! Hansen, 59, is the mother of two daughters and resides in Connecticut with her husband, the iconic Keith Richards. Of their unlikely pairing, Richards wrote in his autobiography, quoting from his 1980 journal: “I’ve met a woman! Unbelievably she is the most beautiful specimen in the WORLD. But that ain’t it! It certainly helps, but it’s her mind, her joy of life and (wonders) she thinks this battered junkie is the guy she loves.”

For her part, Boyd, 71, who entranced not just one but two legends—George Harrison, who wrote “Something” for her, and Eric Clapton (she was the actual Layla)—is now a memoirist and photographer. When she was asked what she thought her special magic was, what made two world-class musicians dissolve at her feet, Boyd was at a loss. She once told ABC News' Elizabeth Vargas, "I wish I knew. Like, I wish I could tell you. I don't know."
